The SleepSurface™ is made of fully breathable polyester mesh and allows all gases/fluids/allergens to pass through. This combined protection gives your baby/child the best opportunity to avoid allergens linked to Asthma and Eczema. HDM allergens are a contributory factor in 70% of childhood eczema and asthma cases. The PurFlo® Mattress also prevents the pooling of exhaled carbon dioxide and makes it less likely that this will be re-inhaled. All these features make the PurFlo® mattress the safest, most comfortable and hygienic mattress you can offer your baby/child. |
